First, your calculator is way off. According to coinwarz, if I were on a multipool, 30MHs makes about $10 to $15 a day. Second, FTC gets in the range of $7 to $10 most of the time. I can also rent my hardware at betarigs and others for $6 to $9 a day. As for trust, I participate in project oriented forums and have not done as much posting here.
I was looking at coinwarz too

That's the CATcoin. I was on CAT for holding. I have about 10K CAT that I plan on keeping. I do FTC now. Fact is, CAT is more volatile (less average earnings in USD) than FTC and worth less than FTC by a factor of 6.
I am a busy poster on the forums.feathercoin.com site.
<- 0.015 per day = $6.60 a day. Already have a customer.
Once the first rental finishes, I'll raise the price.
